Okay - I've got a pair of floorstanding Infinity Entras (the two ways...) up front, and an Entra Center... The rears and back are some older Infinities that I already had. I've decided that I'd like to put the older Infinities in a different room. Here's the fun part. Can't buy Infinity Entras anymore. Will their new models (alpha or primus?) match well? Figuring on getting some nicer floorstanding for the front, and moving the others to the back. Suggestions?
